Abstract
PURPOSE: To investigate hemodynamic response to volume replacement with saline solution and hypertonic hydroxyethyl starch in hypovolemic dogs. METHODS: Forty dogs under general anesthesia and hemodynamic monitoring, following measurements at baseline, were bled 20 ml.Kg-1 and parameters were measured again after 10 minutes. The animals were randomly divided in two groups and volume replacement was performed with saline solution twice the volume removed or 4 ml.Kg-1 of hypertonic hydroxyethyl starch. Hemodynamic data were again measured after 5, 15, 30, 45 and 60 minutes. RESULTS: With both solutions values returned to satisfactory hemodynamic levels. With saline solution, there was a greater amplitude in variations that tended to decrease progressively. With hypertonic hydroxyethyl starch, the parameters studied returned more rapidly to levels similar to those at baseline and varied less. CONCLUSION: Both solutions proved to be efficient at replacing volume in the short period studied, although hypertonic hydroxyethyl starch produced more stable results.
OBJETIVO: Avaliar em cães hipovolêmicos as respostas hemodinâmicas da reposição volêmica com solução salina e hidroxi-etil amido hipertônico. MÉTODOS: Quarenta cães sob anestesia geral e monitorização hemodinâmica, após medidas em repouso foram sangrados 20 ml.Kg-1 e tiveram os parâmetros novamente medidos após 10 minutos. Os animais foram aleatoriamente divididos em dois grupos nos quais foi realizada reposição volêmica com solução fisiológica duas vezes o volume retirado ou 4 ml.Kg-1 de hidroxi-etil amido hipertônico e os dados hemodinâmicos medidos novamente após 5, 15, 30, 45 e 60 minutos. RESULTADOS: A reposição volêmica com as duas soluções fez os valores retornarem a níveis hemodinâmicos satisfatórios, a amplitude das variações com solução fisiológica foi maior, mas tendeu a diminuir progressivamente, com o hidroxi-etil amido hipertônico os parâmetros estudados retornaram a semelhantes ao repouso mais rapidamente e variaram menos. CONCLUSÃO: Ambas soluções se mostraram eficientes na reposição volêmica, o hidroxi-etil amido hipertônico proporcionou resultados mais estáveis.
